K and I had pizza for dinner. This is often a delicate negotiation process. The problem is that once the word 'pizza' has been said aloud, even just as part of a question, there is no going back. So it goes along the lines of: I don't want to cook tonight. Do you think you might feel like cooking? If not, I could give you a call just before I head home, to see what you want to do.
This at least leaves the appearance of the option of one of us being virtuous by cooking something.
And no, I don't think it would work if we spelled it out, like some people do with dogs and the exciting word that starts with 'w'. We never bother to spell it with Mia and Elvis because that would be a waste of good entertainment. They don't even need the actual word, just something that sounds similar-ish, as long as it is in the right kind of sentence. They can always be relied upon to go nuts in response to: Mia, do you want to have a little talk? And my favourite: Elvis.... are you ready to ROCK?!
